Butkus has handled most of the quarterback duties this year, completing 82 of 132 pass attempts for 1,071 yards and running for 508 yards and 13 touchdowns on 104 carries.

Junior Marko Boricich handled the snaps in practice Tuesday. The 6-foot-2, 181-pound Boricich has completed 7 of 10 attempts for 89 yards this season. Lenti called him a capable backup who can stretch the field with his passing.

"He did great," Lenti said of Boricich's Tuesday practice. "He's a bigger kid than Don. He's a very good drop-back passer. He brings a different dimension to the game. He's a pitcher on the baseball team."
